Property sale LTCG tax payment

I am closing my 54A capital gains account as the 2 year time limit from date of sale is over.

I have to pay LTCG tax on this Long Term Capital Gain.

Under what heading and section do I pay this tax online? 

Is it to be paid as Advance Tax or as Self Assessment Tax?

Early advice would be much appreciated
